' VALVE. I

I, HIRAM. S. RANKIn, a cit zen of the Unitedtstates and aresident of Cripple Creek, in the county ofTellerand State of Colorado, have made certain. new and useful Improvementsin This invention 13 a cock'or valve articucom ressed' air or steam. ut the valve is not united to such use, as lt-maybe employed in various (places, in fact anywhere anangle valve is use especially on lines transmitting considerable pressure. 1

In addition to its invention combines therewith the function of V a lubricator, acting under the pressure of the 1 with tion'with the de line or system to force oil to the working surfaces of the valve and also into the pipe and thence to the machine or device operated by the fluid.

A further obj ect or result of the invention is to produce animproved self-seating valve which will not leak, and which receives the fluid pressure internally in both 0 'en and closed positions so. that there is no anger of collapsing the, lug by pressure on .the outer surface thereo which is a defect incident to ordinary plu' 'onl when c osed.

The valve herein disclosed is also provided adjusting means to prevent sticking or difiicult manipulation, which is a point which also has to be considered with valves controllin heavy ressure; urther eatures of the valve are its compactness and rotection from injury, and a construction w the plug when 0 en; also a swiveling connecivery hose or pipe, allowing it to swing to any position without leak.

- The invention is'illustrated in the accom the nipple to swivel in the pan gdrawings in which Fig ure 1 is a central vertical sectlon of the I valve, the plug or valve prpper being adjusted, to open the assa e. section with. va ve c osed.

Both the barrel 8 .and the lug 14 have lateral 0 enings l6 and 17 which by the operation oi the plug are either opened or closed to start or sto the flow. I

(Elsi) integral with the globefi is female member '18 of the outlet pipealiilon, into which the opening 16 leads. of this member 1s shaped to form a tight joint against the outer surface of the barrel 8, around the hole 16, and saidmember'is internally threaded to receive the reamed bushing 19 which fits over the swaged or flared end of the'outlet pipe or nip le' 20 to which the delive hose 1s attache leading to the drill or 01; or machine. This allows joint, the integral pressure preventing leak.

The barrel 8 has a drilled port 21, and the The inner face plug 14 a drilled port 22 which register when the valve is closed. These ports are located to open into the top of the globe or casing IOO ' Fig. 3-at a registers with the groove above the oil, so that when the valve is closed the Oll receives the pressure in the line. Near the bottom of the casing the barrel has another port 23 which, when the valve is closed, opens into one end of a segmental groove 24 formed in the outer surface of the plug 147 This groove is of pro er. length to communicate at its other en When the valve is open, with a passage 25 formed in the inner surface of the barrel 8 and leading upwardly to the outlet opening 16, and also with a passage 26 formed in barrel 8-see point a little nearer the passage 25 than passage 23, and extending below the end of plug 14, as shown in Figs. 3 and 1 so that air has access to it at all times.

The operation of the valve is similar in general to that of any angle cock. As to the lubricating feature when the valve is closed the port 22 registers with the port 21 as shown in Fig. 2. and admits air into the globe 6 above the oil. The port 23 then also 24 in plug 14, and oil is thus forced by air pressure into said groove, When the valve is opened, as shown in Fig. 1, the ports 22, 21, and 23 are closed, and the groove 24 connects the pas sages 2-5 and 26, so that the oil in the groove passes out intothe delivery pipe 20. The oil also finds its way to and between the surfaces of the barrel and plug, thus lubricating the same. I g

The pressure on the plug 1s internal, both when the valve is open and. closed. The valve is self seating and packing, in consequence of its tapered shape and the-action oi the spring 12. Adjustment of the bushing 11 prevents sticking and diflicult action, by easing the pressure on the plug, with the yielding action of the spring 12. The valve and lubricator are combined in a compact form, and the former is protected by the with the interior of the valve when it is open,

as described 2. The combination,with a casing adapted to contain oil and having a lateral o ening, of a tapered barrelS which extends t rough the walls of the casing, a tapered valve arranged rotatably in said barrel and fitted thereto, both valve and barrel being pro vided with openings at the side and bottom and means for securing the valve in the barrel, substantially as described. v

3. The combination with a casing adapted to contain oil, of an angle cock which is located within the casing, comprising a barrel and a hollow turning plug therein, the barrel and plug having ports which are located near the top of the casing and register when the valve is closed, to admit pressure into the casing, the plug having also a segmental groove in the outer surface thereof, and the barrel having a port which opens at the bottom of the casing and registers with the groove when the valve is closed and also havinga passage 25 which opens into the main way of the valve and another 26 that registers with the groove in the plug when the same is open. 4
